The software industry is, by far, one of the businesses that have been introducing most of the major innovations in the modern world (WIPO 2016). Software development Software engineering Project management Engineering management Cost estimates By comparing the estimated values with the actual required data, we found a magnitude of relative error (MRE) of 40% and provided alternatives for future work in order to increase the effort estimation accuracy in safety-critical software projects. The rationales for each scale factor and effort multiplier selection were also described in detail. We applied the method as it is, by correlating the effort multiplier factors with the complexity and objectives introduced by the DO-178C level A application, resulting in an estimated effort. The main goal and contribution of the case study is to support the research on software effort estimation and to provide software practitioners with useful data based on a real project. Systems Engineering Cost Model (COSYSMO), which is installed withĬostar has been largely superseded by SystemStar, which has moreįeatures, and implements more estimating models.This paper provides a real example of applying COCOMO II as an estimation technique for the required software development effort in a safety-critical software application project following the DO-178C processes. SystemStar supports the original COSYSMO model and the latest COSYSMOĬOSYSMO is described in Dr. SystemStar supports the traditional COCOMO, and the most recent models:Ĭlick here for an Overview of COCOMO. Read a brief history of COCOMO for a summary.

Software Engineering Economics and Software Cost Estimation with COCOMO II.ĬOCOMO has continued to evolve and improve since its introduction. Software project managers use SystemStar to produce estimates of a project'sĮxperiment with 'what-if' analyses to arrive at the optimal project plan. To learn about SystemStar before you download it, check out theĬOCOMO is the world's most widely used software estimation model.

We plan to implement the COCOMO III and COSYSMO 3.0 models as SystemStar lets you make trade-offs and experiment with 'what-if' analyses to arrive at a satisfactory project plan.

Engineers use SystemStar to produce estimates of a project's cost. Barry Boehm and the Constructive Systems Engineering Model (COSYSMO) created by Dr. SystemStar is a cost estimation tool based on the Constructive Cost Model (COCOMO®) created by Dr.
